Preparatory winding type camera

Abstract

A preparatory winding type camera wherein one frame is rewound after the whole film in the patrone is previously wound up, and thereafter, the film is automatically rewound into a patrone frame after frame each time a shutter release is performed. During the winding of the film at the time of the preparatory winding processing, a central processing unit causes a liquid crystal display device (LCD) to display the number of film frames always smaller one frame than the normal display, and, when one frame is rewound after the whole film in the patrone is wound up, the number of film frames currently displayed on the LCD is maintained as it is. With this arrangement, the number of film frames displayed on the LCD can avoid the up-down fluctuations during the preparatory winding processing.

I claim: 
     
       1. A preparatory winding type camera comprising: a film winding means for electrically winding a film from a patrone;   a film rewinding means for electrically rewinding the film into the patrone;   a film delivery control means for controlling the film winding means and the film rewinding means in such a manner that one frame is rewound after the whole film in the patrone is wound up during the preparatory winding processing and one frame is rewound each time a shutter release is performed after the completion of the preparatory winding;   a film counter adapted to be counted up each time one frame is wound after the film in the patrone is wound by a photographing prohibiting region during the preparatory winding processing and to be counted down each time one frame is rewound;   a display means for displaying the number of film frames on the basis of the count value in the film counter; and   a control means for controlling the display means in such a manner that a value smaller by one than the count value is displayed as the number of film frames at the time of count-up in the film counter during the preparatory winding processing and the display of the number of film frames is maintained as it is at the time of rewinding by one frame during the preparatory processing.   
     
     
       2. A preparatory winding type camera comprising: a film winding means for electrically winding a film from a patrone;   a film rewinding means for electrically rewinding the film into the patrone;   a film delivery control means for controlling the film winding means and the film rewinding means in such a manner that one frame is rewound after the whole film in the patrone is wound up during the preparatory winding processing and one frame is rewound each time a shutter release is performed after the completion of the preparatory winding;   a film counter adapted to be counted up each time one frame is wound after the film in the patrone is wound by one frame more than a photographing prohibiting region during the preparatory winding processing and to be counted down each time one frame is rewound;   a display means for displaying the count value in the film counter as the number of film frames which can be photographed; and   a control for controlling the film counter in such a manner that count-down in the film counter is prohibited only when one frame is rewound during the preparatory winding processing.
